APPLICATION FILED OUT.28, 1904.

2 SHEETS-SHEET 2 @LW/immo@ taohment oi' said rods trom the cams. ltwill thus be evident that by turning; the shaft the vl'ront ends olf the tracks will be raised and lowered.

ln connection with the hase member there. is employed a table member comprisinga top 35, ijn'eferahly in the l`orm ol a pool or billiard tableand having' an angular ('lciiending flange 36. ln the end portions o' this flange is journaled a shaft $3?, extending' longitudinally beneath the table-top and arranged centrali),Y tl'iereot', said sha'lt having' wheels or rollers 38, rigidly hated thereto and operating' on the tracks i9, the rollersl having' annular retaining-flanges 39. The movement of these rollers on the track is limited by stops l0, formed by upturnino' the ends ot said tracks. '.lhc table member is thus adapted to be placed in an upright position behind the base member when 'thc rollers are at the rear ends of the tracks in roar ot their pivotal supports, said table memberswinging' directly upon the sha'tt and rollers. ./"it the saine time it may be riradily swing to a substantially horizontal position and placed centrally over the base member, the tracks being elevated. Vllhen in this latter position, as shown in liig. i, the said table member can be lirinly :et upon the base member by rotating the sha'lt i253, so that the tracks are depressed.v thus pern'iit'tinig' the end portions et' the iiangg'e 3o' to rest dat upon the supporting-arms. This movement oi? the shaft preferably secured by means of a. crank-arm, (indicated in dotted lines in Fig'.

and designated ik) which eranlrg-arm provided with a suitable socket to receive angular and prel'erably n'nan'iental l'zeads l/l, located on the ends ot' the shalt outside ol: the ends ot' the base l'nomber. Suitable washerselfl are interposed between the heads and adjacent arm portions to cover the openings 29.

For the iurpose oi rigidly securing' the table member on the base member when the Vformer is in operative position there/over locking' devices are employed consisting' in the present embodiment ol shanks Iil., pivotally connected at their lower ends and, as shown at flo, to the inner sides of the elevating-rods F51. The upper ends ol these shanks have transversely-disposed heads 6, terminating' in outer teeth Ll?, tl it are arranged to engage in sooke's fill, 'hin'med in the inner sides ol" the wheels 3S, said sockets thus torming' ilaiiig'es #29, with which the said teeth will interlock. Tl

ne inner sides ot' the heads are provided with under inclined portions 5l), and located in the paths oit movement ot' said inclined portions are inclined ways 5l., formed in the opper portions ot' the inner Walls 1:3 elE the trame, said vvays slidably receiving' the Shanks elfi. Sljn'ings 5&2, interposed hetweei'i the elevating-rods 231 and sl'ianks, serve to urge said shanks outwardliv away Vtrom the wheels. "dfitl'i this sln'ucture it will he apparent that when the table member :is run to a position over the base member the sockets i8 ol5 the wheels will be in line with the teeth si of the locking devices, and when the tracks are depressed the said locking,` devices will move drnvnwardly with them. The inclined portions 50 thereupon will ride down the inclined ways 5i, and the locking devices will be positively moved in an outward direction and into interlocking' engagement With the wheels. liurthermore, as illustrated in Fig. :5, the tracks are preferably arranged to move away from the wheels after the end portions of the [la-nge 3G rest upon the arm. llhis serves to draw the looking' devices downwardly, so as to place strain thereon, and thus more securely bind the tabletop. t the same time the inner portions of the heads ride down past the inclined portions oi the Ways, so that the said looking devices are positively held in their operative positions.

Vihcn the article ot Jfurniture is to oe used as a so't'a, the table member is ot course moved to its upright position in rear of the base member, as shown in Fig'. 2, and in order to cover the tracks and at the same time form a cushioned arm cap-pieces 3 are employed, which rest directly on the 'flat tops ot the arms and have longitudinally-disposed recesses il'in their under sides that receive the tracks, said recesses being' preferably made deeper at their rear om s., as shown at to receive thc rollers. For the purpose oiY fastoning' these caps in place socketpieces are carried by the liront upper corners of the arms, the sockets 57 thereof being' arranged to receive headed studs 5S, located at the upper front ends ot the caps. i/Vhen these caps 'aro placed in position, their rear ends bi snugly against the under side or front sid ol'l the table member, this binding' engagement serving to throw the headed studs 5S forward, so that they will interlock with the socket members. in this structure the mechanism for operating' the table member is very simple, can be easily actuated, is not exposed, and is not liable to derang'ement. rlhe detachable caps necessary to cover the arms are simple, realily positioned, and yet are securely held in place. vrShe lockinp' means is inu'iortant, as it prevents any danger et the table-top being accidentally moved or displaced when in use; but at the same time when the table-top is unlocked it may be lilted bodily from the base member '.vithont interference.

From the foregoing' it is thought that the construction, operation, and many advantages oi'v the hcrein-desoribed invention will be apparent to those 'killed in the art without linz'- ther description, and it Will be understood that various changes in the sine, sh pe, proportion, and minor details oi consti' uction may be resorted to Without departing' from the spirit or sacrilieing any oi' the advantages ol the invention,
